What are Blood Types 1, 2 and 3?

[Scaught]

I did a websearch and couldn't find anything about this. Apparently this is the system in Ukraine. So what's A, B, AB and O?

Thank you for this information. It turns out that my fiancee and I have the same blood type. I expected to find this somewhere on the web in English, but apparently this isn't the case. Have a great weekend and thank you for additional info Cold Warrior.

A blood group or blood type is based on the presence or absence of two proteins (A, B) on the surface of red blood cells. Because two proteins are involved, there are four possible combinations or blood types (ABO groups):

Type A - Only the A protein is present.
Type B - Only the B protein is present.
Type AB - Both proteins are present.
Type O - Neither protein is present (about 40 percent of the population).

In addition to the A and B proteins, there is another protein involved called the Rh factor (Rh for Rhesus monkey, where it was first identified). The Rh factor is either present (+) or absent (-). Therefore, blood types are described as the type and Rh factor (such as O+ , A+, AB-).
